Patented Mar. 24, 1936 UNITED STATES PATENT OFFICE 2 Claims.

One object of this invention is the provision of a device or machine fordestroying grasshoppers and similar pests which infest farmlands andcause extensive destruction of crops, the device serving to kill thelarvae and the young of the insects.

Another object is the provision of such a device in the form of a draftvehicle adapted to be drawn over a field by draft animals or automotivepower.

A further object is the provision of such a vehicle with a drum orroller having prongs or teeth extending radially from its peripheralsurface, the prongs digging into the earth as the roller passesthereover and crushing both the insects and their larvae, as well astheir eggs.

The above and other objects will become apparent in the descriptionbelow, in which characters of reference refer to like-named parts in theaccompanying drawings which form a part of this specification.

Referring briefly to the drawings, Figure 1 is an underside plan view ofthe device.

Figure 2 is a cross-sectional view taken on the line 22 of Figure 1.

Figure 3 is a cross-sectional view taken on the line 33 of Figure 1.

Referring in detail to the drawings, the numeral ID represents asubstantially rectangular horizontal frame having the four sides I I,l2, l3, and 14. These sides of the frame are firmly interlocked by meansof screw threads on the ends of the members [3 and I4, and nuts l5threaded thereon to clamp the members H and I2 thereagainst. The sidemembers II and I2 are of triangular shape, with the central dependingtip [6 having a bearing therein in which an axle I1 is rotatablymounted. A horizontal frame member I8 is integral with the side membersH and I2 and provides a platform which covers the members mountedtherebeneath. On this platform I8 is mounted the drivers seat I9.

A hollow roller 29 is integrally mounted about the axle H. The entireperipheral surface of the roller 2i! has teeth 2| extending therefrom.These teeth taper toward their extremities and their ends are flattened.

A brush 22 whose bristles are shown at 23 is mounted on the underside ofthe platform l8 directly above the roller 20. The bristles 23 are madeof rather stiff material.

In use, the vehicle is drawn over the field, 5 whence the roller 20rotates. In doing so, the teeth 2| dig into the earth and crush theyoung grasshoppers, their larvae, and their eggs, at the same timedriving the crushed remains into the earth. The brush 22 serves to cleanthe teeth 10 prior to their next contact with the earth as the rollerprogresses.

It is thus apparent that a device has been provided which serves toeffectively kill and destroy grasshopper pests before they reachmaturity. 15 By destroying these insects while they are young, not onlythe destruction which they cause is prevented, but also themultiplication of the insects through reproduction later if they werepermitted to live.

Obviously, modifications in form and structure may be made withoutdeparting from the spirit of the invention.

I claim:

1. A draft vehicle comprising a rectangular frame having a platformthereon, a roller rotatably mounted in said frame under said platform,radial teeth projecting from the surface of said roller and adapted todig into the earth as the 30 roller turns, and a brush mounted undersaid platform and over said roller to clean the teeth of the roller.

2. A draft vehicle comprising a rectangular frame having a platformthereon, a drivers seat 35 mounted on said platform, a roller rotatablymounted in said frame under said platform, radial teeth projecting fromthe surface of said roller and adapted to dig into the earth as theroller turns, said teeth tapering toward their extremities and .10having flattened ends, and a brush mounted between said platform androller to clean the teeth of the roller as the latter turns.
